Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31449536, here are decompositions:

37 + 31449499 = 31449536
43 + 31449493 = 31449536
73 + 31449463 = 31449536
127 + 31449409 = 31449536
163 + 31449373 = 31449536
277 + 31449259 = 31449536
373 + 31449163 = 31449536
409 + 31449127 = 31449536

Showing the first eight; more decompositions exist.
